Turn GitHub into your personal Skills library
People pay $10/month for a 'format converter' that's just FFmpeg with a GUI. They pay API costs for models they could run locally for free.
GitHub has 30 years of open source tools sitting there, but most people can't use them. Deployment is difficult, everything requires command line, and environment setup tends to kill projects before they start.
AI coding agents changed this. Any open source project can become a Skill, which is basically a packaged capability an agent calls whenever you need it.
Packaging open source as Skills
Any GitHub project can now be packaged as a Skill an agent calls on demand. You find the tool by asking any model to search GitHub, feed the repo to a coding agent, let it package the project as a callable Skill, fix edge cases on the first run, and then you have that capability going forward.

yt-dlp has 143k stars and supports 1000+ video platforms. FFmpeg and ImageMagick handle basically any format conversion. ArchiveBox saves web pages however you want. A project with 50k stars is more stable than anything an AI generates on the fly.
Open source models running locally
The models are going open source too. GLM-4.7 hits 73.8% on SWE-bench, which puts it in real coding agent territory. Qwen, DeepSeek, Mistral are all competitive with frontier models, with open weights and permissive licensing.
Ollama makes local inference straightforward. One command to install, one to pull a model. You can run inference on a MacBook in about five minutes. An M2 with 16GB RAM handles 7B models, and a gaming PC with a decent GPU handles 30B+ parameter models that compete with GPT-4 on coding tasks.
The full local stack
Skills are local scripts. Local models run local inference. The whole pipeline from prompt to tool execution to output stays on your machine. Proprietary workflows stay proprietary. Sensitive data stays local. If a company changes their pricing or deprecates an API, it doesn't affect you.
So you end up with open source tools from GitHub, open source models running locally, and Skills connecting them. You control the whole stack.
Three years ago, using FFmpeg meant digging through Stack Overflow and memorizing cryptic flags. Now you say "convert this to MP4", and a local model calls the Skill.
